A Possible Rossby Wave Instability Origin for the Flares in Sagittarius A*
Michel Tagger, Fulvio Melia
In recent years, near-IR and X-ray flares have been detected from the Galaxy's central radio point source, Sagittarius A* (Sgr A*), believed to be a \~3.10^6 solar masses supermass…
A Persistent High-Energy Flux from the Heart of the Milky Way : Integral's view of the Galactic Center
Guillaume Belanger, Andrea Goldwurm, Matthieu Renaud +6
The Ibis/Isgri imager on Integral detected for the first time a hard X-ray source, IGR J17456-2901, located within 1' of Sgr A* over the energy range 20-100 keV. Here we present th…
Spin-Induced Disk Precession in Sagittarius A*
Gabriel Rockefeller, Christopher L. Fryer, Fulvio Melia
In Sgr A* at the Galactic center, by far the closest and easiest supermassive black hole we can study, the observational evidence is increasingly pointing to the presence of a comp…
Long-Term Radio Modulation in Sagittarius A* from Spin-Induced Disk Precession
Martin Prescher, Fulvio Melia
There is some evidence, though yet unconfirmed, that Sagittarius A*--the supermassive black hole at the Galactic center--emits its radio waves modulated with a ~100-day period. Wha…
The X-ray Ridge Surrounding Sgr A* at the Galactic Center
Gabriel Rockefeller, Christopher L. Fryer, Frederick K. Baganoff +1
We present the first detailed simulation of the interaction between the supernova explosion that produced Sgr A East and the wind-swept inner ~ 2-pc region at the Galactic center.…
The Sgr B2 X-ray Echo of the Galactic Center Supernova Explosion that Produced Sgr A East
C. L. Fryer, G. Rockefeller, A. Hungerford +1
The possible impact Sgr A East is having on the Galactic center has fueled speculation concerning its age and the energetics of the supernova explosion that produced it. We have ca…
